Correct Answer

C. (60)

Step 1

Concept

(Z(1)+Z(4)=(b-6)+(b-24)=2b-30). From (2b-30=90), (b=60).

Step 2

Why this answer is correct

The correct answer is C. (60). (Z(1)+Z(4)=(b-6)+(b-24)=2b-30). From (2b-30=90), (b=60).

Step 3

Exam Tip

(Z(1)+Z(4)=(b-6)+(b-24)=2b-30) है। (2b-30=90) से (b=60) मिलता है।
